4. Newton’s 1st law states that a body at rest or uniform motion will
continue to be at rest or uniform motion until and unless a net external
force acts on it.
5. LET US UNDERSTAND IT BETTER WITH
AN EXAMPLE
• Newton’s First Law of Motion Examples in Daily
Life
• Wearing a seat belt in a car while driving is an
example of Newton’s 1st law of motion. If an
accident occurs, or if brakes are applied to the car
suddenly, the body will tend to continue its
inertia and move forward, probably proving fatal.
To prevent such accidents seat belts are used
which stops your body from moving forward in
inertia avoiding danger.

7. Newton’s 2nd law states that the acceleration of an object as produced
by a net force is directly proportional to the magnitude of the net force,
in the same direction as the net force, and inversely proportional to the
mass of the object.
8. LET US UNDERSTAND IT BETTER WITH
AN EXAMPLE
Two people walking among the two people
walking, if one is heavier than the other then
the one weighing heavier will walk slower
because the acceleration of the person
weighing lighter is greater.

10. The Newton’s 3rd law states that for every action there is an equal and
opposite reaction
11. LET US UNDERSTAND IT BETTER WITH
AN EXAMPLE
• The flight of the bird is an example of an
action-reaction pair. The wings of the bird
push the air downwards. The air pushes the
air upwards.
